[Q] *#*# codes

Hey everyone,
Does any one know how to get codes like *#*#4636#*#* to work?
Id like to poke around within the network settings and also check out the wifi signal strength.
When i try the code above nothing happens. However the thunderbolt 4g switcher app in the market allows me to bring up the radio menu

I'm not sure this has everything you're looking for, but try ##PROGRAM

UseAnyCut from the market to set a shortcut to any of the hidden menus, no keycodes needed.

##program still 000000
##program password is still 000000

Thanks i dident know this phone had the ##program code still in it. That will work fine

##PROGRAM is for the CDMA radio programming.
Anyone tried *#*#4636#*#* code (this is Android's networking test/settings menu). I wonder if there is way to switch phone to GSM mode

Hi leo like I said above, you can get to all the menus easily with shortcuts but GSM mode is disabled in the radio so that won't work.
All of the low level settings menus are available though.

Thanks CZ, I miss the good old days when TBH was overflowing with moto leaks.. I'd imagine uncrippled radio

Oh how I miss those days too...waiting for the full xml.zip for the D4 so we can have some fun with it safely is killing me!
I expect there to be an update that unlocks the GSM global roaming capability soon,we'll see.

GSM requires more than a simple "unlock" - Motorola makes multiple different sets of radio firmware for this hardware. The GSM firmware is completely separate and totally absent from our radio image.

Can the gsm firmware be added somehow? It is the only way I'll ever be able to use this phone with my provider.
And it's not like I have any other good options for dual core sliders...

Droid 3 is a dual core slider with full GSM global capability and will be much easier to get working anywhere you might be than the D4.
There are rumors about GSM being enabled in the firmware with an update, but the radios are signed images and virtually impossible to write your own or even a modified image.

[Q] is there a way to force LTE?

like my phone can just sit on 3G, in the same place,while not moving
but if i reboot my phone, it'll pop on to LTE (if its available in that area)
but i reboot it in known LTE areas (when showing 3G)
anyway to force LTE, without rebooting the phone?
or is there some time schedule where it checks to see if LTE is available that I can change?

Yes which model u have? Its in the secret menu

I don't have the Sprint version so I don't know if this works but you can try https://www.youtube.com/watch?v=bSrtUw8D9_w as this method worked for the very similar LG G2 for Sprint.

I feel for you buddy because this phone is blazing fast on LTE

Hahaha you're absolutely right. I knew just by reading the thread. Sprint is the worst! My HTC One on Sprint was amazing but I couldn't ever hold on to an LTE connection for more then 30 seconds. Unlimited data is useless if your only on their horribly slow 3g

Sprint does suck, if i didnt have 4 other people on my account that would have to get new phones/account etc, I would have been switched.
but that video i think was to turn on LTE, my LTE is on, but for some reason wouldnt search/connect to LTE when it was available all the time
however i went into my mobile connection settings, and changed it from "LTE/CDMA" to Global
now it seems to switch to LTE when its in an LTE area. LTE icon comes up without me having to reboot, i'll keep a watch on it for a few days to see if indeed that was the solution
by the way, anybody now what the "global" option is? compared to LTE/CDMA

I'm pretty sure the global setting is to allow it to connect to GSM carriers in the event that the device is unlocked and the APN is changed accordingly.

I have the same problem in brazil, looks like a problem with the Phone. I had a Samsung S4 that worked with full signal in 4G in my home, now that I moved to LG G Flex it also works full signal 4G in home, but when I move to some place where is Edge then go Back to home, it never moves back to LTE automatically. I need to restart or change the NetworkMode manually to make it back working in 4G.
I think the phone has a problem to automatic search and change the Network mode.

anyone know how to enable only lte yet? i've tried all different kinds of secret menu codes and cant figure it out.

Answer
How to access the hidden service menu on LG G Flex:
For AT&T: Go to dialer and enter 3845#*950#
For T-Mobile: Go to dialer and enter 3845#*959#
For Sprint: Go to dialer and enter 3845#*995#
Once you're in the hidden menu, go to LTE-Only > Modem Settings > RAT Selection > LTE only
Enjoy!

Pair 10 pro with AT&T Number Sync successful

So sorry if this was common knowledge but I haven't seen anything on this yet so I thought I'd share. I decided to try setting up AT&T's number sync between my new mate 10 pro and my LG Sport and it worked. What makes that amazing is this is the first non att branded phone I have ever been able to set up directly between the phone and a att smartwatch that didn't require me using a att branded smartphone in the middle. You can't find the ability to do it through the my att app or website but if you initiate through the watch, it will open the browser on your phone and then give you a number sync code, once you log in through the browser, you put in the code and then accept terms and it will successfully link. This phone also seems to work well with the LG Sport. Battery life is waaay better then when it's paired to my Att Note 8.
FYI, Att number sync allows multiple devices to receive a phone call or text message from the main line they are tied to. That way every thing is seen from one number. One of the requirements is that the phone must be Att branded.
So that tells me between this and VoLTE working on att with this phone, this phone was all but ready for att network and only thing missing was the att branding on the phone before att backed out.
Sorry if long l, just wanted to share to maybe help other att users.

Have you been able to get/verify that VoLTE is working on your mate 10 Pro? If yes, how did you verify it works? I have a Dual Sim 10 Pro rebranded to the US 10 Pro (did at Best Buy) with the Enhanced Voice and VoLTE options enabled. Thanks.

I didn't use the default apn that sets up when I had my att sim inserted. I used the settings from att's support page: https://www.att.com/esupport/article.html#!/wireless/KM1218306
If I remember, there were a few subtle differences. Honestly, I didn't notice if VoLTE was working before the new apn settings but I see that it works for sure with the new apn settings. My status doesn't change from LTE whether on call and/or browsing.

well, not working for me... i used an app to validate data connection during phone call and when connected to a call, data drops to HSPA+.

Hmmm...visually the LTE symbol dosesnt change and I think it sounds like it should. What's the app you used? I'll check and see if I get the same thing.

So I made a phone call with the app running and it showed under the raw tab:
Voice NW: LTE
Data NW: LTE+
So I'm guessing its working.

No problem. I was thinking, you said you rebranded to us but I wonder if by a slim chance there is some hardware difference that is dectected? Like maybe a certain band att uses. I haven't looked at the differenceces in bands between models.

Cellular bands are the same as US version; when not in a call I connect to LTE+. I can achieve cellular download speeds of 98 Mbps. Main difference between US version and mine is my phone is dual SIM Mate 10 Pro. The second SIM connects to 4G when I make a call. If I use only 1 SIM, connection drops to HSPA+. I see an option to enable VoLTE on the second SIM, but it's disabled. Have you to find a way to enable it. I appreciate your feedback, thanks again.

As you probably know, mine only has one Sim slot and when I go to settings and drill down into the mobile network options, under 'Advanced' Enhanced LTE Services is already enabled.

How to force 4g LTE on sim 1 or sim 2 as needed?

I am using the dual sim Exynos version of Note 9 and want to be able to force 4g LTE on either of the two sims as needed.
Can someone please advise how to do this on an unrooted phone? Thanks

Anyone?
I also found no solution. I think it's possible without root but no one is updating the Phone Information Apps. We need to get access at phone information 2 and not only on 1

Mine are both 4G / LTE. Inever need to switch the Sims around. Whichever I choose for days gets LTE. this is different from what I had in the Note 8. I was pleasantly surprised. Therefore it may be a settings issue for you. I have the Note 960F/D

you may try quickshortcutmaker app on exynis version and follow instructions in video
https://youtu.be/AdGAB4qRvYA

I feel like the Tasker App could handle this easily.

I dont understand the actual need.
Simply changing preferred network mode from LTE to 3G shall do to stop LTE on any sim.
I use LTE on both sims for calls
I use LTE for data on specific sim by making it as preferred sim for data.
Settings -- Networks -- Sim card manager shall help in these settings.
I am on exynos N960F Indian firmware.

You don't understand the actual need ??
So i will tell you
On my work i am located in a big Hall underground. The Provider i need down there is only coming in with -110 dB and less which is one LTE Bar. If i leave Automatic Mode it switches always in 2g Mode because of much higher Signal. So to get a nice experience and have LTE always available there is no other solution. The same kind of problem is on my other LTE Sim when on different Locations during the Day ! So i have no time to always switch sim cards so that sim2 is forcing lte !
And off course no one else knows this and so i benefit of this extremely fast connection where all others are crying because of no 4g connection

OK understood.
Did not you get one UI already which has option of LTE only selection too for network mode.

Negative. Here the German Rom (dbt csc unbranded)
Has never got LTE Only mode in the menu. This is also for all European Roms. I have had this only when using Root and Custom Roms.
Because i use many banking and streaming apps it's not possible to root this time. Even with Magisk Hide they will not work.
If i could i would have rooted long time ago. This is getting me Crazy really

Sorry but are you reading my Post?
I am talking LTE Only on Sim Slot 2 of any Samsung Phone out today. All the LTE Only Apps or the Phone Info Menu where they lead you is only working on Sim Slot 1.
I am sure there is a dial code like the one it gets you to the Phone1 Information Screen where you can change the bands. But only for Sim 2 (Phone info 2) on Samsung.
So again LTE Only on sim Slot 2 on Samsung Duos Versions is not Possible @ the moment without Root!
If there is any Dev out there you would be the first One to create an app where Phone INFO 2 is possible to change! Or just find the right hidden code for that i know it's there like the Phone Information 1

Hi,
There's an option to force the selected APN to LTE only but I don't know if it will behave like you want to.
What's great is that it's per SIM so you can try any combinaisons.
Deselect "undefined" and select only the "LTE" one (screenshots).
I expect that if it find any other bands getting a better signal than LTE, it will just let the phone loss the signal and not trying to catch the LTE one, but you can try.

Hey thanks for that. I really was in hope this could work but that would have bean to easy. Unfortunately it's not changing bands after deselecting undefined and than choose some network mode it remains to the same band but it looses the mobile data symbol (but still remains in same band).

This code and all Codes are not working on European Samsung Devices with Android 9 .
I Even Rooted my Galaxy Note 9 and all the hidden codes are Not working ! Even Samsung Phone Info App or other Apps are not working with Latest Android 9.
Only way is Root and Custom Rom like Alex Dev Rom where the CSC is Modified. There it was possible to change both Sim to LTE Only ! But as told before with Root
i loose to many services which are detected even with Magisk . So my next Phone will not be Samsung anymore because of that.

Question oneplus 10 cdma setting?

so im kinda desperate, so sorry for this post.
according to many places like gsm, his phone should be able to work with cdma networks
i waited months for it to arrive to yemen, so i cant return it
amazingly beautiful phone, but what's the point without using calls
also when i dial the phone info code *#*#4639#*#* to change the network, nothing appears
other codes, except checking imei also dont work
but as if there is a restriction to it, is there anyways to get access to it?

On GSMArena shows that it support CDMA but I don't know if it's only for specific OS variant, as I understand CDMA is used only for 2G and 3G so you probably need to check if your carrier let you enable VoLTE .
The menu *#*#4636#*#* was disabled/hidden since OOS 12 we can't mess with that right now.
